Society we live in now is waaaaaaaaaaaaaaaaaaaay better than, say, five hundred years ago. We've got indoor plumbing, electricity, medicine, and in many places, housing standards and labour laws.
Whether or not all this nice stuff is just a big conspiracy for The Man to earn more money off us is irrelevant. Life is better than it was before, period.
Discrimination is still a problem, but you can't deny that it's a much smaller problem, especially in the more developed nations (of which I assume you live in, given your access to western television and the internet.)
Oh, you think so? Well, then I must surprise you. It is still a problem. A huge one. For example, people who are working at certain jobs treated like untocheable, low sort, scum. Just because they don't have a fancy job in some kind of high-class business or whatever.
And don't even get me started with any others kind of discrimination. No matter where you live. Just in some countries this problem is even worse than in the others. But as a whole, humanity is still in the late medievals, when it comes to social progress.
I live in New Zealand, where racism amounts to complaining about all the Chinese shops in Riccarton, and maybe if we're feeling really discriminatory, making jokes about Australians being stupid. It is not at all "medieval".
Granted, other countries are different, but just because you can't see the progress doesn't mean it isn't there.
WWII resulted in the deaths of approximately 60 million people. World population after the war was approximately 2.5 billion.
The biggest war of all time took out just over two percent of the world's population.
The English Civil War, which was mentioned above, killed 190 thousand people. England's population at that time is estimated to be 5 million.
A war that took place in a small corner of the globe took out three and a half percent of the country's population.
I'm probably going to go into a ridiculously in-depth analysis comparing the two conflicts now.
